ABSTRACT

Various other methods, systems, and computer-readable media are also disclosed.

BACKGROUND

Malware can cause serious problems for computing systems, and the detection of malware poses a difficult challenge as malicious software constantly evolves. Data mining solutions have sometimes been used to analyze various data on a computing device in the effort to detect malware. Traditionally, data mining techniques use structured data analysis to detect patterns and anomalies that can explain various phenomena. By using data analysis to detect patterns based on known malware, these solutions may be able to use similar patterns to also detect the potential for new instances of malware. Thus, these solutions may provide better security by recognizing signs of malware that may not yet be known.

However, some data is not easily analyzed by traditional data mining methods. For example, data that is not easily labeled or that does not conform to a standard format may be difficult for traditional methods to process. In some cases, the information that may be extracted from this data is lost in the process of formally defining strict categories used to classify whether the data may indicate malware. At the same time, other methods that may be able to process this data may not be able to process more complex, structured data that could provide more detailed analyses of malware. Because of the difficulty in mining both unstructured and complex data, more advanced solutions are needed to accurately detect computer malware. Accordingly, the instant disclosure identifies and addresses a need for additional and improved systems and methods for identifying malware through data mining methods.

SUMMARY

As will be described in greater detail below, the instant disclosure generally relates to systems and methods for detecting malware using machine learning by combining deep learning neural networks with supervised data mining methods. The disclosed systems may use the combination of techniques to create a classifier to detect malware. Additionally, these systems may classify data about a computing device to determine whether the computing device is infected with malware. Furthermore, the disclosed systems may then use security measures to combat a potential malware threat.

In one example, a computer-implemented method for detecting malware using machine learning may include (1) identifying data to be analyzed for malware, (2) classifying, using a classifier created by a combination of at least one deep learning neural network and at least one supervised data mining method, the data to be analyzed for malware, (3) determining, based on a predefined threshold, that the classification of the data indicates potential malware on the computing device, and (4) performing a security action based on the determination of potential malware on the computing device. In some examples, identifying the data to be analyzed for malware may include identifying data on the computing device, receiving data from a client device, and/or downloading data from a network.

In one embodiment, the deep learning neural network may include multiple layers of artificial neural networks configured to accomplish hierarchical feature extraction, semi-supervised machine learning, and/or unsupervised machine learning. In an additional embodiment, the supervised data mining method may include a decision tree, a vector machine, a supervised neural network, an ensemble method, and/or regression analysis.

In one example, the combination of the deep learning neural network and the supervised data mining method may include feature extraction with the supervised data mining method and classification of features with the deep learning neural network. In this example, the feature extraction with the supervised data mining method may include converting training data into leaf nodes and converting the leaf nodes into features using a bag-of-words model. In another example, the combination of the deep learning neural network and the supervised data mining method may include feature extraction with the deep learning neural network and classification of features with the supervised data mining method.

In some embodiments, classifying the data to be analyzed for malware may include predicting the classification of the data to be analyzed for malware with the classifier created using training data. In these embodiments, the training data may include an example of malware, an example of safe software, data about a computing system infected by malware, and/or data about a computing system without malware. Additionally, in other embodiments, the predefined threshold for classification may include a degree of likelihood that the classification of the data to be analyzed for malware accurately identifies malware.

In one example, the computer-implemented method may further include creating a new classifier, using the combination of the deep learning neural network and the supervised data mining method, with updated training data. In this example, the updated training data may include new training data gathered periodically and/or addition of the data to be analyzed for malware.

In one embodiment, a system for implementing the above-described method may include (1) an identification module, stored in memory, that identifies data to be analyzed for malware, (2) a classification module, stored in memory, that classifies, using a classifier created by a combination of at least one deep learning neural network and at least one supervised data mining method, the data to be analyzed for malware, (3) a determination module, stored in memory, that determines, based on a predefined threshold, that the classification of the data indicates potential malware on the computing device, and (4) a security module, stored in memory, that performs a security action based on the determination of potential malware on the computing device. In addition, the system may include at least one processor that executes the identification module, the classification module, the determination module, and the security module.

In some examples, the above-described method may be encoded as computer-readable instructions on a non-transitory computer-readable medium. For example, a computer-readable medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (1) identify data to be analyzed for malware, (2) classify, using a classifier created by a combination of at least one deep learning neural network and at least one supervised data mining method, the data to be analyzed for malware, (3) determine, based on a predefined threshold, that the classification of the data indicates potential malware on the computing device, and (4) perform a security action based on the determination of potential malware on the computing device.

Furthermore, exemplary system 100 may include a security module 110 that may perform a security action based on the determination of potential malware on the computing device. Although illustrated as separate elements, one or more of modules 102 in FIG. 1 may represent portions of a single module or application.

In certain embodiments, one or more of modules 102 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing device, may cause the computing device to perform one or more tasks. For example, and as will be described in greater detail below, one or more of modules 102 may represent software modules stored and configured to run on one or more computing devices, such as the devices illustrated in FIG. 2 (e.g., computing device 202 and/or server 206), computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7. One or more of modules 102 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks.

As illustrated in FIG. 1, exemplary system 100 may also include one or more databases, such as database 120. In one example, database 120 may be configured to store training data 122, which may be used in machine learning to recognize malware patterns. Additionally or alternatively, database 120 may store classifier 124, which may then be used to detect potential malware.

Database 120 may represent portions of a single database or computing device or a plurality of databases or computing devices. For example, database 120 may represent a portion of server 206 in FIG. 2, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7. Alternatively, database 120 in FIG. 1 may represent one or more physically separate devices capable of being accessed by a computing device, such as server 206 in FIG. 2, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7.

Exemplary system 100 in FIG. 1 may be implemented in a variety of ways. For example, all or a portion of exemplary system 100 may represent portions of exemplary system 200 in FIG. 2. As shown in FIG. 2, system 200 may include a computing device 202 in communication with a server 206 via a network 204. In one example, computing device 202 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120. Additionally or alternatively, server 206 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120.

In one embodiment, one or more of modules 102 from FIG. 1 may, when executed by at least one processor of computing device 202 and/or server 206, enable computing device 202 and/or server 206 to detect potential malware using collected data. For example, and as will be described in greater detail below, identification module 104 may identify data 208 to be analyzed for malware. Classification module 106 may classify, using a classifier 124 created by a combination of at least one deep learning neural network and at least one supervised data mining method, data 208 to be analyzed for malware. Determination module 108 may determine, based on a predefined threshold 212, that a classification of data 210 indicates potential malware on computing device 202. Security module 110 may perform a security action 214 based on the determination of potential malware on computing device 202.

In the example of FIG. 2, and as will be explained in greater detail below, training data 122 may first be used to create classifier 124 that classifies potential malware. Identification module 104 may identify data 208 about computing device 202. For example, identification module 104 may collect data about software running on computing device 202. Classification module 106 may then obtain classifier 124 from server 206 via network 204 and classify data 208 with classifier 124 to determine if data 208 may indicate malware on computing device 202. Next, determination module 108 may use predefined threshold 212 to decide that classification of data 210, which classifies data 208, indicates potential malware. Finally, security module 110 may respond to the potential malware infection with security action 214.

Computing device 202 generally represents any type or form of computing device capable of reading computer-executable instructions. Examples of computing device 202 include, without limitation, laptops, tablets, desktops, servers, cellular phones, Personal Digital Assistants (PDAs), multimedia players, embedded systems, wearable devices (e.g., smart watches, smart glasses, etc.), gaming consoles, combinations of one or more of the same, exemplary computing system 610 in FIG. 6, or any other suitable computing device.

Network 204 may facilitate communication or data transfer using wireless or wired connections. In one embodiment, network 204 may facilitate communication between computing device 202 and server 206.

FIG. 3 is a flow diagram of an exemplary computer-implemented method 300 for detecting malware using machine learning. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1, system 200 in FIG. 2, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7.

As illustrated in FIG. 3, at step 302, one or more of the systems described herein may identify data to be analyzed for malware. For example, identification module 104 may, as part of computing device 202 in FIG. 2, identify data 208 to be analyzed for malware.

Identification module 104 may identify data 208 in a variety of ways. In some examples, as shown in FIG. 2, identification module 104 may identify data 208 by collecting data 208 from computing device 202. In other examples, identification module 104 may receive data 208 from a client device to be analyzed. In further examples, identification module 104 may download data 208 from network 204. In these examples, the downloaded data may include data or software obtained from online marketplaces, such as an app store. Alternatively, identification module 104 may reside separately from computing device 202 and may receive data 208 from computing device 202.

Returning to FIG. 3, at step 304, one or more of the systems described herein may classify, using a classifier created by a combination of at least one deep learning neural network and at least one supervised data mining method, the data to be analyzed for malware. For example, classification module 106 may, as part of computing device 202 in FIG. 2, classify, using classifier 124, data 208 to be analyzed for malware.

Classification module 106 may classify data 208 in a variety of ways. In one embodiment, the deep learning neural network may include multiple layers of artificial neural networks configured to accomplish hierarchical feature extraction, semi-supervised machine learning, and/or unsupervised machine learning. The term “artificial neural network,” as used herein, generally refers to a model of connected data that is weighted based on input data and used to estimate a function. For example, a deep belief neural network may use unsupervised training of input data to detect features within the data. The term “feature extraction,” as used herein, generally refers to a process of deriving values or vectors that can be analyzed as part of machine learning. Furthermore, in an additional embodiment, the supervised data mining method may include a decision tree, a vector machine, a supervised neural network, an ensemble method, and/or regression analysis.

As used herein, the term “decision tree” generally refers to predictive models with a branching structure that graphs outcomes of observations. The term “vector machine,” as used herein, generally refers to learning models that use algorithms to recognize patterns for classification. The term “supervised neural network,” generally refers to artificial neural networks that use labeled training data to estimate functions. Furthermore, the term “ensemble method,” as used herein, generally refers to combinations of learning algorithms that improve the predictive power of models. Additionally, as used herein, the term “regression analysis” generally refers to statistical models of expected relationships between dependent and independent variables. Additionally or alternatively, other similar data mining methods using supervised machine learning may be used.

In some examples, the combination of the deep learning neural network and the supervised data mining method may include feature extraction with the supervised data mining method and classification of features with the deep learning neural network. In these examples, the feature extraction with the supervised data mining method may include converting training data into leaf nodes and converting the leaf nodes into features using a bag-of-words model. The term “leaf node,” as used herein, generally refers to a data value or condition without a child node and used as a part of a tree data structure. The term “bag-of-words model,” as used herein, generally refers to a representation of data, particularly text, that may track the presence or frequency of different data (e.g., words) within each document and may weigh them by importance to convert them to features.

For example, as shown in FIG. 4, a supervised data mining method 402(1) may convert training data 122 into leaf nodes 410. A bag-of-words model 412 may then convert leaf nodes 410 into features as part of feature extraction 404(1). Next, a deep learning neural network 406(1) may be used to process the features as part of classification of features 408(1) in order to create classifier 124.

In other examples, the combination of the deep learning neural network and the supervised data mining method may include feature extraction with the deep learning neural network and classification of features with the supervised data mining method. In the example of FIG. 4, a deep learning neural network 406(2) may be used for feature extraction 404(2) of training data 122. A supervised data mining method 402(2), which may include regression analysis 414, may then be used for classification of features 408(2) to create classifier 124.

Additionally, classifier 124 may be created with alternate combinations of one or more supervised data mining or deep learning methods. Multiple classifiers may also be created using various combinations of methods, and the best classifier may be selected as classifier 124. Furthermore, classifier 124 may be created on server 206, created on computing device 202 and stored on server 206, and/or created on another computing device and stored on server 206.

In one embodiment, and as shown in FIG. 2, classification module 106 may classify data 208 to be analyzed for malware by predicting classification of data 210 with classifier 124 created using training data 122. In this embodiment, training data 122 may include an example of malware, an example of safe software, data about a computing system infected by malware, data about a computing system without malware, and/or any combination of the above. In the example of FIG. 5, training data 122 may include data about a malware 502(1), a malware 502(2), a safe software 504(1), a safe software 504(2), a safe software 504(3), an infected computing system 506(1), a safe computing system 508(1), and a safe computing system 508(2).

Returning to FIG. 3, at step 306, one or more of the systems described herein may determine, based on a predefined threshold, that the classification of the data indicates potential malware on the computing device. For example, determination module 108 may, as part of computing device 202 in FIG. 2, determine, based on predefined threshold 212, that classification of data 210 indicates potential malware on computing device 202.

Determination module 108 may determine that classification of data 210 indicates potential malware in a variety of ways. In some examples, predefined threshold 212 may include a degree of likelihood that classification of data 210 accurately identifies malware. For example, classifier 124 may be determined to accurately identify malware in a certain percentage of cases, and classification of data 210 may pass predefined threshold 212 if the percentage is high enough. In another example, classification of data 210 may represent a likelihood of data 208 indicating malware, and predefined threshold 212 may be used to determine if the likelihood is high enough. Furthermore, multiple classifiers may result in different classifications of data 208, and predefined threshold 212 may determine the best classification to be used in detecting malware on computing device 202.

Returning to FIG. 3, at step 308, one or more of the systems described herein may perform a security action based on the determination of potential malware on the computing device. For example, security module 110 may, as part of computing device 202 in FIG. 2, perform security action 214 based on the determination of potential malware on computing device 202.

Security module 110 may perform security action 214 in a variety of ways. In one example, security module 110 may attempt to mitigate the potential malware threat on computing device 202. Additionally or alternatively, security module 110 may notify a user or administrator of computing device 202 about the potential malware. In examples where data 208 is received from a client device, security module 110 may perform security action 214 on the client device.

In some embodiments, one or more of the systems described herein may create a new classifier, using the combination of the deep learning neural network and the supervised data mining method, with updated training data. Furthermore, in these embodiments, the updated training data may include new training data gathered periodically and/or addition of the data to be analyzed for malware. In the example of FIG. 5, new training data 500 and data 208 may be added to training data 122 to create a new classifier 510. New training data 500 may add additional example data of a malware 502(3), a safe software 504(4), a safe software 504(5), and a safe computing system 508(3). Data 208 may include data for an infected computing system 506(2), such as computing device 202. New classifier 510 created from the updated training data may then be used to classify future data to be analyzed for malware.

As explained above in connection with method 300 in FIG. 3, the disclosed systems and methods may, by using deep learning methods to support and enhance traditional data mining techniques, create a classifier to detect malware on computing devices. For example, the systems and methods described herein may use traditional, supervised machine learning to extract features from training data, such as a collection of documents with identifiable tokens that may be converted to features through a bag-of-words model. Subsequently, a deep learning system, such as a deep belief network, may be trained to classify the features extracted from the training data.

Alternatively, the disclosed systems and methods may use deep learning as a way to preprocess the training data. In this example, deep learning may be able to process unlabeled data that traditional methods cannot, and the results of a deep learning system may then be used as features to be analyzed by a traditional method. The classifiers created through the above methods may be updated by using updated training data. The disclosed systems and methods may further use the classifiers created in the above examples to classify data about a specific computing device in order to analyze the device for malware. Additionally, the systems and methods disclosed herein may perform a security action if the classification of the data determines that there is a potential malware threat.

As detailed above, by using both traditional machine learning and deep learning methods, the disclosed systems and methods may be able to better analyze complex and unlabeled data to train a process to detect malware. In addition, the disclosed systems and methods may better classify data to be analyzed for malware using a classifier resulting from the trained process. Thus, the systems and methods described herein may create classifiers that detect malware more accurately than traditional means.
